Summary of R. capsulatus Bioscreen growth curves

The previous post (GTA competition experiments) described the results of the follow-up set of R. capsulatus growth curves that I planned at the end of the previous experiment (R. capsulatus growth curves in RCV medium). But it didn't pull together the results of all the Bioscreen growth curves, nor integrate them with what was previously known/thought). So here goes:

First, what's already been reported about growth in liquid culture? Not a lot. The graphs below are all I could find. (I asked my colleague here - he says he doesn't know of any others.)

GTA production:

The only work that measured GTA production along with growth is Solioz et al. 1975, and their 'growth curve' is just a schematic. The titers of GTA this shows are very peculiar. The titer is very low while the culture is growing, and rises to about 3x10^4 just before culture density levels off. But then it dips sharply, falling to about 10^3 over a few hours, and then rises again to its final stable level of about 4x10^5.
